I have been having issues with stuttering under load through the middle of the RPM curve. Checked a million things so far but no solution. Did some logs a couple weeks ago and everything looked good, fuel pressure, boost, n75...when it would stutter it was pulling massive timing i.e. -8* which is the only thing that looked off.
Tonight we logged LPFP duty cycle at idle and made a couple 3rd gear pulls. The duty cycle at idle was in the 48-50% range and at WOT it would reach 85%.
I searched and couldn't find what the duty cycle should be. Right now we are leaning towards a clogged fuel filter or the LPFP going bad.
Speaking of the LPFP where can I get one and how much do they normally cost. I couldn't find any online unless I can run a walbro 255?
Thanks.
